In a voltaic cell electrons flow from the anode to the cathode. true or false

Answers

True , In a voltaic cell, the anode is the electrode where oxidation occurs and electrons are produced. The cathode is the electrode where reduction occurs and electrons are consumed.

The electrons flow from the anode to the cathode through an external circuit, which generates an electric current. This flow of electrons is what produces the electrical energy in the cell.

In a voltaic cell, also known as a galvanic cell, a spontaneous redox reaction occurs, which results in the conversion of chemical energy into electrical energy. This redox reaction involves the transfer of electrons from one substance to another.

The electrons produced at the anode flow through the external circuit to the cathode. This flow of electrons is driven by the difference in electric potential between the anode and the cathode.

This potential difference is often referred to as the cell voltage or electromotive force (EMF) of the cell.

As the electrons flow through the external circuit, they produce an electric current, which can be used to power electrical devices.

Meanwhile, the redox reaction continues within the cell, with electrons being transferred from the anode to the cathode via an ionic bridge or salt bridge, which allows the movement of ions between the two half-cells to maintain charge neutrality.

Overall, the flow of electrons from the anode to the cathode through the external circuit is what produces the electrical energy in a voltaic cell.

The orbits of planets being elliptical was one the planetary laws developed by

Answers

The correct answer is Kepler

Final answer:

The concept that planets move in elliptical orbits was established by Johannes Kepler in his First Law of Planetary Motion. This significant idea disrupted the earlier belief of circular orbits and brought tremendous knowledge in our solar system understanding.

Explanation:

The fact that the orbits of planets are elliptical was part of the planetary laws developed by the renowned astronomer and mathematician Johannes Kepler. Damaging the former belief of circular orbits, Kepler, based on detailed and exhaustive astronomic observations, established his First Law of Planetary Motion which stated that planets move in elliptical orbits with the Sun at one of the two foci. This was a significant breakthrough in understanding our solar system and continues to be fundamental in physics and astronomy today.

An electromagnetic wave has a frequency of 2.90 × 1014 Hz. What is the wavelength of the wave? Question 17 options: 1.03 × 10–6 m 9.60 × 10–7 m 8.70 × 1022 m 2.61 × 10–21 m

Answers

Answer:

Wavelength of the wave is $1.034 * 10^(-6) m$

Explanation:

Wavelength of the wave is given by

$\lambda=(v)/(f) \n$

Here,

$f=2.90* 10^(14) Hz\nv=3* 10^8 m/s$

wavelength is

$\lambda=(v)/(f) \n\lambda=(3 * 10^8)/(2.90* 10^(14))\n\lambda=1.034 * 10^(-6) m$

Option A is correct

A car is traveling with an initial velocity of 15 m/s when the driver decides to go faster by accelerating at 5 m/s squared for 10 seconds. How far did the car travel during this time?

Answers

Answer:

x = 400 [m]

Explanation:

To solve this problem we must use the following kinematics equations, first, we find the final speed, and then we proceed to find the distance traveled.

$v_(f)=v_(i) +(a*t)\n$

where:

Vf = final velocity [m/s]

Vi = initial velocity = 15 [m/s]

a = acceleration = 5 [m/s^2]

t = time = 10 [s]

Note: the positive sign in the Equation indicates that the car is accelerating, i.e. its speed is increasing.

Now replacing

Vf = 15 + (5*10)

Vf = 65 [m/s]

Now using the second equation:

$v_(f) ^(2)= v_(i) ^(2)+(2*a*x)$

where:

x = distance traveled [m]

x = (65^2 - 15^2)/ (2*5)

x = 400 [m]
